Ibn `Umar was told that Abu Huraira said, "Whoever accompanies the funeral procession will have a reward equal to one Qirat." Ibn `Umar said, "Abu Huraira talks of a too enormous reward." Aisha attested Abu Huraira's narration and said, "I heard Allah's Messenger (ﷺ) saying like that." Ibn `Umar said, "We have lost numerous Qirats."

← Previous Hadith Ash-Shu`bi said, "Somebody who passed along with your Prophet (p.b.u.h) by a grave that was separate from the other graves informed me (saying), "The Prophet (ﷺ) led us (in the prayer) and we aligned behind him." We said, "O Abu `Amr! Who told you this narration?" He replied, "Ibn `Abbas."

Sahih al-Bukhari Book 23, Hadith 79 Next Hadith → that Allah's Messenger (ﷺ) (p.b.u.h) said, "Whoever attends the funeral procession till he offers the funeral prayer for it, will get a reward equal to one Qirat, and whoever accompanies it till burial, will get a reward equal to two Qirats." It was asked, "What are two Qirats?" He replied, "Like two huge mountains."
